To all "whom it may concern:

Be it known that I, WILLIAM. BEALL GnAr, a citizen of the United States, and a resident ofLouisville, in the county of 'Jefierson and Stateof Kentucky, have invented i certain new and useful Improvements in Pipe-Supports, speoification.'

, My invention is an improvement in pipe supports, and has for its object the provision of a safe and simple device of the character specified, for supporting heating and power pipes, wherein means is provided of which the following is a for permitting the expansion and contrac-- tion of the pipes without injury to the said pipes or to the support.

Referring to the drawing forming a part -ther'eof:Figure 1 is a side view of the improvement; Fig. 2 is a bottom plan view of I, v ing over th pipe 2, and engaging the tudinal series f transverse rack teeth 5, the"? said series bein divided from-each other by a longitudinal .rib 6, which extends below the face of the teeth, as shown more particularly in Figs. 1 and 3;

for t A roller is provided, 'the said roller hav ing a central opening 8 for receiving a shaft 9, and having a plurality of annular series ofv gear teeth 10, separated and spaced from each other by an annular groove 11. The teeth '10 fit the teeth 5, and the rib 6 fits the groove 11.-It will be noted also that the teeth of the series 10 are of greater length than the'teeth of the series 5, so that the said teeth extend beyond the sides of the carriage as shown in Fig.3. The opening 8 he shaft. 9 is of greater diameter than the shaft, except at the ends of the roller, atwhich point the roller ,fits the shaft closely. A'collar 12 is arranged'on the shaft at each end of the roller, the said collar holding the roller from longitudinal movement "on the shaft.

.Each collar is held in place against the ends of the roller bymeans of struck up spurs 13 or thelike. The con-.

duit 14 in which the pi e 2 and the support are arranged is provi ed on each side of the central line of its bottom with a rib 15, each of the said ribs having a horizontal upper face and a vertical inner face, and being'integral with the conduit. The said ribs are provided-at each shaft 9, with oppositely arranged notches 16, for receiving the ends of the shaft. The said notches are-of a depth approximately equal to that" of the shaft, and are of sufiicient length to provide 2 a clearance between the ends of theshaft, and the inner ends of the notches.

When the pipe 2 expands or contracts the saddle or carriage moves therewith, and the tates the-roller 7, and the shaft 9, the said shaft rotating in the notches 16. The pipe is thus while perfectly. supported capable of longitudinal movement in'either direction,

without any possibility of injuring the conduit or the pipe.

It will be understood that the saddle is shaped on its upper face to fit the pipe 2, or the insulation of-the said pipe when the pipe carries insulation. The saddle may be also provided with my improved anchoring means shown in my rior application, Serial No. 709,262, filed Ju y 13, 1912, when carrying insulated pipe.

It will'be evident that the shaft might be integral with the roller, 01' might be secured theretoiin any other suitable manner. The projecting ends, of the shaft'are' in'fact ournal pins for the roller, for engaging the supports in the conduit. The shaft 9 does not necessarily rotate, as the roller may be arranged to rotate on the shaft.

I claim:'

1. Incombination with the conduit, a device of the character specifie..;, comprising a carriage for the pipe, the upper face of 'the carriage be1ng concave transversely t0 fit the pipe to besupported, said carriage having on its under face a longitudinal central rib, and a series of gear teeth on each side of the rib, a roller provided with an annular groove for receiving the rib, and with an annular series of gear teeth on each side of the rib, to fit the teeth of the carriage,

said roller having a central longitudinal bore, the ends of the bore being restricted, a shaft received in the bore and fitting the said movement of the carriage or saddle ror estricted ends, a collar on theshaft at each end of the roller, said shaft having struck' up lugs for holding the collars from outwardmovement, the conduit having a longitudi-.

nally extending rib on each side of the central line' of its bottom, eachrib having a horizontal upper face and a vertical inner face, said ribs having oppositely arranged notches for receiving the ends of the shaft.

2. A device of the character specified';'comprising a carriage for the pipe, the upper face of the carriage being concave transversely to fit the pipe to :be supported, said carriage having on'its under face a longitudinal central rib, and a series of gear teeth on each side of the rib, a roller provided with an annular groove for receiving the rib, and with an annular series of gear teeth on each side of the rib, -to fit the teeth of the carriage, sald roller having a central longitudinal bore, the ends of the bore being restrictcd, a shaft received in the bore and fitting the restricted ends, a collar on the shaft at each e d of the roller, saidshaft having 'struck 111 lugs for holding the collars from outward movement, the ends of the shaft extending beyond the collars.

3. A device of the character Specified, comprising a carriage for the pipe, the upper face of the carriage being concave transversely to 1% the pipe to be supported, said carriage having on.its under face a longitudinal central rib, and a series of gear teeth on each side of the rib, a roller provided with an annular groove for receiving the rib, and with an annular series of gear teeth on each side of the rib, to fitthe teeth of the. carriage, and a shaft for the roller, said shaft extending at its ends beyond the ends of the roller and having means for preventing longitudinal movement of the roller.

4. A device of the character specified, comprising a carriage for the pipe, the upper face of the carriage being concave transversely to fit the pipe to be supported, said carriage having on its under face a longiof the rib, the rib dependingbelow the te'eth,

and a roller having'an annular series of gear teeth for each series of the carriage, and an annular groove between the series for receiving the rib, and having an axial jour-' nal pin for the purpose specified.

6. A device of the character specified, comprising a carriage for the pipe, said carriage having laterally spaced longitudinal series of gear teeth, a roller havin an annular series of gear teeth for each series of the carriage, and having an axial journal pin at each end, and means for preventing lateral movement of the carriage with respect to the roller.

7. A device of the character specified, comprising a carriage, having a longitudinal series of, gear teeth, a roller having an annular series of teeth fitting the teeth of the carriage, and having an axial journal pin at each end, and means in connection with the carriage and the rollerfor preventing lateral movement of the carriage.
